I've just installed a wireless USB dongle and I have an odd problem, the dongle is only detecting networks broadcasting on channel 1. Luckily, my router just happens to be on channel 1 at the moment, however if that changes my computer simply won't see it!
I've tried 4 different wireless devices now, 2 Ralink PCI wireless receivers, 1 Ralink USB receiver and now a sitecom USB receiver. All of the receivers I've tried have wireless b/g/n support. All of them have had the same problem.
I have a wireless g router.
What could be causing this, and how can I go about fixing it?
Additional details as people have asked for in the comments. Router is on b/g "mixed mode", laptop is on windows 7 professional 32 bit, PC is windows 7 professional 64 bit. The laptop is right next to the PC and can pick up 20 networks (including my own), the PCcan only detect two networks, both on channel 1. Signal strength to my own network from the PC is very good.
